Resona Health Company History

Resona Health is the trading name of Sly As A Fox, LLC, a Florida company run from Cocoa Beach by Mark L. Fox and Barbara Fox. Mark Fox, who by his own account spent 17 years as an aerospace engineer, says he turned to energy therapy after his dog was diagnosed with arthritis.

The brand went online in 2020, and by February 2023 the VIBE, a PEMF device that fits in a pocket, was on sale with a wholesale program for practitioners. It is designed in the United States and made in China. The range has since grown to the BlueVibe and the VaguVibe, kits for dogs and horses, creams and a wellness watch.

HSA / FSA

Depends on Your Plan

An HSA or FSA holds money set aside before tax, so spending it on something the account covers saves you the difference. Resona Health names no HSA service to go through, so whether the VIBE qualifies is up to your plan administrator, and you claim the money back after you buy.

  • 1Ask your plan administrator whether the VIBE qualifies before you buy.
  • 2Get a letter of medical necessity from your provider if the plan asks for one.
  • 3Send the claim to your plan with your receipt.

Their help center suggests describing the VIBE to your plan as similar to a TENS unit, and says most insurance plans don’t cover it.

Resona Health Ratings, Reviews and Complaints

Trustpilot

Scamadviser

Safe

site verdict

Not a customer rating

This one scores the website rather than the company, on things like SSL, hosting and traffic, and it calls resona.health very likely legitimate. The two things it marks down are low traffic and the site’s own review system.

BBB

A+

BBB rating

1

complaint

Accredited since July 2026. The one complaint, from October 2025, was about an order placed twice by mistake. The company says it refunded one of the two, and BBB lists it as answered.

Resona Health FAQ

No. Resona Health sells its devices as general wellness products. Its help center calls the VIBE “an FDA-recognized general wellness device”, but the same answer says it is not a medical device, and every page on the site carries the line that its claims have not been evaluated by the FDA.

A search of the FDA’s 510(k) database finds no clearance under the Resona name.

In China. The VIBE is designed in the United States, and their help center says it is built by manufacturing partners that specialize in electronics, with some parts sourced from Asia.

Mark Fox puts it more simply in an interview: the VIBE is made in China, the same as almost every electronic device in your home.

Yes. The company behind it, Sly As A Fox, LLC, has been on the Florida register since 2009, is still active, and is based at 203 Rose Drive in Cocoa Beach. It is BBB accredited with an A+ and holds 4.7 out of 5 on Trustpilot from 623 reviews.

It owns no registered trademark. Its one application, for Resonance Frequency Therapy, was filed in 2020 and abandoned in 2021. The privacy policy also names the company as SAAF, LLC, the initials of Sly As A Fox.

Mark L. Fox and Barbara Fox, the two managing members of Sly As A Fox, LLC on the Florida register. Mark Fox is the founder and CEO, and the face of the brand in its videos and podcast interviews.

The site calls him a former Space Shuttle Chief Engineer. In an interview he describes 17 years as an engineer at Morton Thiokol at the Kennedy Space Center, and later work at Iomega. I couldn’t find the chief engineer title confirmed anywhere outside his own site and interviews.

Devices that stop working, and devices that don’t seem to do anything. Among the most recent Trustpilot reviews, one VIBE stopped working after two months and one BlueVibe after a few days. Another buyer sent a BlueVibe back because it came without a printed manual. Most of the other low ratings say they noticed no change, and two reviewers say support was slow to answer.

The BBB has a single complaint, from October 2025, from a customer who ordered twice by accident and couldn’t get an answer about the refund. The company says it refunded one of the orders. On Trustpilot, every negative review has a reply from the company, usually an offer to go through your protocols with you.

From Resona Health directly. The VIBE also turns up at other shops and on eBay, and nothing in their return or warranty answers says whether a unit bought there is covered.

Buying direct keeps you inside the 30 day money back guarantee and the 1 year warranty. Go to the Resona Health shop.

Not that they publish. No financing or pay later option appears on their product pages or in their help center.

If you have an HSA or FSA, whether it pays for the VIBE depends on your plan. You check with your administrator first, add a letter of medical necessity if the plan wants one, and claim the money back with your receipt.
